Ordinoides give birth in very moist areas where there's plenty of humidity/dampness. An expected mother should always have a box with damp newspaper or paper towels but no water dish. IF they have no choice but to use very dry substrate or the humidity is low, the sack will dry out quickly and they'll get stuck and suffocate every time. I even have to mist them every minute or two after they come out and if you can't be there for the birth to help those that struggle, you'll lose a lot of them, if not all.
